John, could you expand on this comment? I use Pan F
almost exclusively when I am working in medium format,
and I love it. Like the original poster, I also sometimes 
see an odd speckling or lumpy grain when scanned
on my Epson 2540 flatbed--for me, this usually shows up
in sky or clouds.

So, why is a ccd scanner especially bad for Pan F? 

Thanks,
David
